The road trip mode could show the route but not what sits beside it, which is half of what planning a drive is about (#1797). The right column becomes a corridor search: pick what you need, pick how far off the route you will go for it, and the day's drive is searched box by box. The boxes come from the route itself rather than the viewport, so the answer is "on the way", not "on screen"; each hit reports how far off the route it lies and how far into the drive it comes, and adding one opens the normal place form so it lands on the day like any other stop. Overpass is asked in plain bounding boxes rather than with a polyline filter, because that is what the existing /api/maps/pois route accepts and what the mirrors can answer; the geometry work is pure and tested. Long routes stop at ten boxes and say so instead of quietly searching half the drive. Fuel, charging, rest areas and campsites join the server's POI categories, so the explore pill and the MCP search_pois tool gain them too. A car booking's stops now also reach the PDF, which printed pick-up and return with everything in between missing.
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.
Not yet here
The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
